Abstract
It is concluded that the annealing time has a relatively considerable effect on the density, hardness and expansion coefficient of the glass but it has a great effect on the longitudinal elastic modulus and bulk modulus of the glass.
It is also concluded that the elastic modulus of glass is strongly dependent on major oxides like Si02/ Ca 0, and MgO due to the relatively high values of number of crosslinks per cation and number of network bonds per unit volume.
There is no observable difference in the IR spectra of more annealed glasses compared to those spectra of unannealed ones.
It has been found that the application of the bond-compression model was so satisfactory to give us the role and influence of each oxide in the commercial soda lime silicate glass.
